Why: Fair use is a well established doctrine, and I am no fan of vendor lockin. How: This utility implements the PID extraction, DRM key generation and decryption algorithms employed by the KindleForPC application. This is a stand alone app that does not require you to determine a PID on your own, and it does not need to run KindleForPC in order to extract any data from memory. Shoutz: The DarkReverser - thanks for mobidedrm! The last part of this is just a C port of mobidedrm. labba and I<3cabbages for motivating me to do this the right way. You guys shouldn't need to spend all your time responding to all the changes Amazon is going to force you to make in unswindle each time the release a new version. CMBDTC - nice work on the topaz break! Lawrence Lessig - You are my hero. 'Nuff said. Cory Doctorow - A voice of reason in a sea of insanity Thumbs down: Disney, MPAA, RIAA - you guys suck. Making billions off of the exploitation of works out of copyright while vigourously pushing copyright extension to prevent others from doing the same is the height of hypocrasy. Congress - you guys suck too. Why you arrogant pricks think you are smarter than the founding fathers is beyond me. */ Rationale: Need a tool to enable fair use of purchased ebook content. Need a tool that is not dependent on any particular version of KindleForPC and that does not need to run KindleForPC in order to extract a PID. The tool documents the structure of the kindle.info file and the data and algorthims that are used to derive per book PID values. Installing: A compiled binary is included. Though it was built using cygwin, it should not require a cygwin installation in order to run it. To build from source, you will need cygwin with gcc and make. This has not been tested with Visual Studio, though you may be able to pile all the files into a project and add the Crypt32.lib, Advapi32 and zlib1 dependencies to build it. usage: ./skindle [-d] [-v] -i <ebook file> -o <output file> [-k kindle.info file] [-p pid] -d optional, for topaz files only, produce a decompressed output file -i required name of the input mobi or topaz file -o required name of the output file to generate -k optional kindle.info path -v dump the contents of kindle.info -p additional PID values to attempt (can specifiy multiple times) You only need to specify a kindle.info path if skindle can't find your kindle.info file automatically
